Here in the eastern part of the US I am always jealous the the variety of hummers in the western half of our country.
I see that Denton, Texas is not far from Dallas - as the hummer flies. Using that information, checking with Wild Birds Unlimited (there is one in Dallas on Lovers Lane
), they advise the early hummers seek the Coral Honeysuckle, Crossvine, Texas Buckeye and Scarlet Buckeye.
Since you relocated from North Carolina and need to learn about Texas gardening, check with Lady Bird Johnson (can't get more Texas that that)

I'm still jealous, but I'll settle for photos of your hummers.
